Comparison analysis performance microstrip antennas for software and measurement

Abstract

In antenna design there are several antenna software that can be used to design for example CST, Microsoft office AWR, Advance Digital Signal (ADS). After calculating using the antenna formula, then it is designed using antenna software. Antennas are printed and measured to determine the performance parameters of the antenna. When designing by calculating using formulas, and software, which is then measured using the Vector Network Analyser (VNA). In this study, it can be seen the level of error using antenna software, as well as measurements on performance parameters. The antenna size is 49x49 mm2 both using antenna software and measurement. The result of performance parameters return loss are-47.43 dB, bandwidth of 163.7 MHz and VSWR 1.009 using software at the frequency 2.4 GHz. The result performance parameters by measurement, return loss decreases to-12 dB, bandwidth of 119 MHz and VSWR 1.111 at frequency 2.334 GHz. The difference in the performance parameter values between software and measurement can be influenced by several factors are when printing antenna, soldering that is to hot causes copper in the antenna to become hot so it affects the propagation of electromagnetic waves.
